5822 | /* And below is a version of the above table that accepts only strict UTF-8. |
5823 | * Hence no surrogates nor non-characters, nor non-Unicode. Thus, if the input | |
5824 | * passes this dfa, it will be for a well-formed, non-problematic code point | |
5825 | * that can be returned immediately. | |
5826 | * | |
5827 | * The "Implementation details" portion of | |
f6521f7c | 5828 | * https://bjoern.hoehrmann.de/utf-8/decoder/dfa/ shows how |
123deead KW |
5829 | * the first portion of the table maps each possible byte into a character |
5830 | * class. And that the classes for those bytes which are start bytes have been | |
5831 | * carefully chosen so they serve as well to be used as a shift value to mask | |
5832 | * off the leading 1 bits of the start byte. Unfortunately the addition of | |
5833 | * being able to distinguish non-characters makes this not fully work. This is | |
5834 | * because, now, the start bytes E1-EF have to be broken into 3 classes instead | |
5835 | * of 2: | |
5836 | * 1) ED because it could be a surrogate | |
5837 | * 2) EF because it could be a non-character | |
5838 | * 3) the rest, which can never evaluate to a problematic code point. | |
5839 | * | |
5840 | * Each of E1-EF has three leading 1 bits, then a 0. That means we could use a | |
5841 | * shift (and hence class number) of either 3 or 4 to get a mask that works. | |
5842 | * But that only allows two categories, and we need three. khw made the | |
5843 | * decision to therefore treat the ED start byte as an error, so that the dfa | |
5844 | * drops out immediately for that. In the dfa, classes 3 and 4 are used to | |
5845 | * distinguish EF vs the rest. Then special code is used to deal with ED, | |
5846 | * that's executed only when the dfa drops out. The code points started by ED | |
a3815e44 | 5847 | * are half surrogates, and half hangul syllables. This means that 2048 of |
123deead KW |
5848 | * the hangul syllables (about 18%) take longer than all other non-problematic |
5849 | * code points to handle. | |
5850 | * | |
5851 | * The changes to handle non-characters requires the addition of states and | |
5852 | * classes to the dfa. (See the section on "Mapping bytes to character | |
5853 | * classes" in the linked-to document for further explanation of the original | |
5854 | * dfa.) | |

45235d99 KW |
6508 | locale for category C<LC_NUMERIC> to be what perl thinks is the current |
6509 | underlying locale. (The perl interpreter could be wrong about what the | |
6510 | underlying locale actually is if some C or XS code has called the C library | |
6511 | function L<setlocale(3)> behind its back; calling L</sync_locale> before calling | |
6512 | this macro will update perl's records.) | |

6537 | This is used to help wrap XS or C code that is C<LC_NUMERIC> locale-aware. |
6538 | This locale category is generally kept set to a locale where the decimal radix | |
6539 | character is a dot, and the separator between groups of digits is empty. This | |
6540 | is because most XS code that reads floating point numbers is expecting them to | |
6541 | have this syntax. | |

6543 | This macro makes sure the current C<LC_NUMERIC> state is set properly, to be | |
6544 | aware of locale if the call to the XS or C code from the Perl program is | |
6545 | from within the scope of a S<C<use locale>>; or to ignore locale if the call is | |
6546 | instead from outside such scope. | |
6547 | ||
6548 | This macro is the start of wrapping the C or XS code; the wrap ending is done | |
6549 | by calling the L</RESTORE_LC_NUMERIC> macro after the operation. Otherwise | |
6550 | the state can be changed that will adversely affect other XS code. | |

7639 | * "nan-ness". Part of the payload is the quiet/signaling bit. | |
7640 | * To back up a bit (harhar): | |
7641 | * | |
7642 | * For IEEE 754 64-bit formats [1]: | |
7643 | * | |
7644 | * s 000 (mantissa all-zero) zero | |
7645 | * s 000 (mantissa non-zero) subnormals (denormals) | |
7646 | * s 001 ... 7fe normals | |
7647 | * s 7ff q nan | |
7648 | * | |
7649 | * For IEEE 754 128-bit formats: | |
7650 | * | |
7651 | * s 0000 (mantissa all-zero) zero | |
7652 | * s 0000 (mantissa non-zero) subnormals (denormals) | |
7653 | * s 0001 ... 7ffe normals | |
7654 | * s 7fff q nan | |
7655 | * | |
7656 | * [1] this looks like big-endian, but applies equally to little-endian. | |
7657 | * | |
7658 | * s = Sign bit. Yes, zeros and nans can have negative sign, | |
7659 | * the interpretation is application-specific. | |
7660 | * | |
7661 | * q = Quietness bit, the interpretation is platform-specific. | |
453b60f1 | 7662 | * Most platforms have the most significant bit being one |
5c255b3b JH |
7663 | * meaning quiet, but some (older mips, hppa) have the msb |
7664 | * being one meaning signaling. Note that the above means | |
7665 | * that on most platforms there cannot be signaling nan with | |
453b60f1 JH |
7666 | * zero payload because that is identical with infinity; |
7667 | * while conversely on older mips/hppa there cannot be a quiet nan | |
7668 | * because that is identical with infinity. | |
7669 | * | |
7670 | * Moreover, whether there is any behavioral difference | |
7671 | * between quiet and signaling NaNs, depends on the platform. | |
5c255b3b JH |
7672 | * |
7673 | * x86 80-bit extended precision is different, the mantissa bits: | |
7674 | * | |
7675 | * 63 62 61 30387+ pre-387 visual c | |
7676 | * -------- ---- -------- -------- | |
7677 | * 0 0 0 invalid infinity | |
7678 | * 0 0 1 invalid snan | |
7679 | * 0 1 0 invalid snan | |
7680 | * 0 1 1 invalid snan | |
7681 | * 1 0 0 infinity snan 1.#INF | |
7682 | * 1 0 1 snan 1.#SNAN | |
7683 | * 1 1 0 qnan -1.#IND (x86 chooses this to negative) | |
7684 | * 1 1 1 qnan 1.#QNAN | |
7685 | * | |
7686 | * This means that in this format there are 61 bits available | |
7687 | * for the nan payload. | |
7688 | * | |
3bbe6a60 JH |
7689 | * Note that the 32-bit x86 ABI cannot do signaling nans: the x87 |
7690 | * simply cannot preserve the bit. You can either use the 80-bit | |
7691 | * extended precision (long double, -Duselongdouble), or use x86-64. | |
7692 | * | |
453b60f1 JH |
7693 | * In all platforms, the payload bytes (and bits, some of them are |
7694 | * often in a partial byte) themselves can be either all zero (x86), | |
7695 | * all one (sparc or mips), or a mixture: in IEEE 754 128-bit double | |
7696 | * or in a double-double, the first half of the payload can follow the | |
7697 | * native double, while in the second half the payload can be all | |
7698 | * zeros. (Therefore the mask for payload bits is not necessarily | |
7699 | * identical to bit complement of the NaN.) Another way of putting | |
7700 | * this: the payload for the default NaN might not be zero. | |
7701 | * | |
7702 | * For the x86 80-bit long doubles, the trailing bytes (the 80 bits | |
7703 | * being 'packaged' in either 12 or 16 bytes) can be whatever random | |
7704 | * garbage. | |
7705 | * | |
7706 | * Furthermore, the semantics of the sign bit on NaNs are platform-specific. | |
7707 | * On normal floats, the sign bit being on means negative. But this may, | |
7708 | * or may not, be reverted on NaNs: in other words, the default NaN might | |
7709 | * have the sign bit on, and therefore look like negative if you look | |
7710 | * at it at the bit level. | |
7711 | * | |
7712 | * NaN payloads are not propagated even on copies, or in arithmetics. | |
7713 | * They *might* be, according to some rules, on your particular | |
7714 | * cpu/os/compiler/libraries, but no guarantees. | |
7715 | * | |
7716 | * To summarize, on most platforms, and for 64-bit doubles | |
7717 | * (using big-endian ordering here): | |
7718 | * | |
7719 | * [7FF8000000000000..7FFFFFFFFFFFFFFF] quiet | |
7720 | * [FFF8000000000000..FFFFFFFFFFFFFFFF] quiet | |
7721 | * [7FF0000000000001..7FF7FFFFFFFFFFFF] signaling | |
7722 | * [FFF0000000000001..FFF7FFFFFFFFFFFF] signaling | |
7723 | * | |
7724 | * The C99 nan() is supposed to generate *quiet* NaNs. | |
7725 | * | |
7726 | * Note the asymmetry: | |
7727 | * The 7FF0000000000000 is positive infinity, | |
7728 | * the FFF0000000000000 is negative infinity. | |
